>> reporter: the administration said that between 2009 and 2011, the chinese government offered up at least $1 billion in subsidies to its auto and auto parts exporters. the u.s. claims those subsidies allowed chinese products to be sold at artificially low prices across the world, altering global trade, and violating the agreements made by members of e wod trade organization, or w.t.o. >> the charge that's being made is that the type of subsidies which the chinese government is offering to a range of companies, chinese companies, are what's called contingent on export, and if that's the case, then that's clearly a breach of the subsidies agreements and china's commitments under the w.t.o. >> reporter: if the accusations are true, the subsidies are not just hurting u.s. manufacturers at home, but also abroad as they sell detroit's finest around the globe. of the $350 billion worth of cars and auto parts produced here last year, $123 billion were exported.
